Some of you may or may not remember a little game that was screwed over big time called:

Vanguard: Saga of Heroes.

In said little niche game, there was a healer called the Disciple. This little Disciple class was basically a monk. It was h2h, kicked and whatnot, but it also did heals as it did damage. Aoe heals, single target heals, whatever. Also, in this game, there was a little class called the Blood Mage. You stole health from the mob to heal your allies. You could also take your own health to heal or get your mana back.

Those two classes were the most fun I have ever had healing in any game up until this date. None of the healing classes in any game come close to how awesome these classes were, and they will never ever be seen in FFXIV.
